Title: Electrostatic charge image developing toner
Inventor: OCHIAI MASAHISA
IPC: G03G9/09
Filed: 2003-03-04
Abstract: <P>PROBLEM TO BE SOLVED: To solve the following problems: the use of carbon black is being restricted, for example, in EC because carbon black falls under materials (IARC group B) as subjects to regulation in terms of effect on the human body and environmental protection, and though magnetite is considered to be a substitute for carbon black, commercially available magnetite for a toner takes on a color tone tinted with red or has insufficient hiding power because it has a volume average particle diameter of 0.1-0.5 μm.  <P>SOLUTION: This electrostatic charge image developing toner consists essentially of a binder resin and a colorant, and is held on a surface of a non-magnetic developing roll. The colorant is based on magnetite consisting of a plurality of groups of particles different from each other in particle size distribution. It is preferable that the magnetite consists of a group of particles having a volume average particle diameter of primary particles in the range of 0.2-0.5 μm and a group of particles having a volume average particle diameter of primary particles in the range of 0.05-0.2 μm.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Filed: 2003-03-05
Abstract: <P>PROBLEM TO BE SOLVED: To perform stable treatment over a long period of time by preventing the lowering of the flux of an RO membrane, in subjecting biological treatment water-containing water to RO treatment.  <P>SOLUTION: The biological treatment water-containing water is adjusted to pH 4-6 to be filtered and the obtained filtered water is subjected to RO treatment. Since protein or the like causing the lowering of the flux of the RO membrane is easily flocculated in the vicinity of pH 4-6, a substance causing the lowering of the flux of the RO membrane such as protein or the like contained in the biological treatment water-containing water can be efficiently trapped and removed by a filter by passing the biological treatment water-containing water adjusted to pH 4-6 through the filter to suppress the lowering of the flux of the RO membrane.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Heat storage device
Inventor: SUGANUMA MAKOTO
IPC: F24H7/02
Filed: 2003-03-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a heat storage device capable of reducing influence of weight of a heat storage material upon expansion and shrinkage action of a heat transfer pipe caused by thermal expansion and preventing breakage and failure of the heat transfer pipe by allowing the action.  <P>SOLUTION: The heat transfer pipe 14 is meanderingly arranged so as to combine a plurality of U-shaped pipes having a curved part and a straight part. The curved part 20a curving and inverting like U shape in the uppermost stream part of the heat transfer pipe 14 is arranged above an upper face of a mixed heat storage material 13. The straight part 19 is arranged inside the mixed heat storage material 13. For this reason, since the mixed heat storage material 13 is not arranged on an upper face of the curved part 20a, movement of expansion and shrinkage caused in the straight part 19 of the heat transfer pipe 14 in the vertical direction is not regulated by weight from above. Consequently, weight burden of the heat transfer pipe 14 for expansion and shrinkage operation on an outer face can be reduced when compared with a case where it is completely buried into the mixed heat storage material 13.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
